San Diego, 650 Gateway Center Dr, San Diego, CA 92102

If you live in Southeast San Diego, Costco Wholesale at 650 Gateway Center Dr is probably your second home. It’s tucked away just off the 94, making it a much more convenient haul than fighting the crowds over in Mission Valley. This location has that classic, high-energy warehouse vibe we all know and love—where you walk in for a single rotisserie chicken and somehow walk out with a 40-pack of sparkling water, a new set of patio furniture, and enough Kirkland Signature snacks to survive an apocalypse.


One of the biggest perks of this specific spot is the gas station. It’s massive, and while there’s almost always a line, the staff does an incredible job of keeping traffic moving so you’re not sitting there forever just to save a few bucks on a fill-up. Inside, the warehouse is laid out really well, with a huge produce section and a deli that stays stocked with those pre-made meals that save us on busy weeknights. Plus, having the Optical Department and a reliable Pharmacy all under one roof makes it the ultimate spot to knock out every errand on your list in one go.


Of course, no trip to this Costco is complete without hitting the Food Court. Whether you’re grabbing a $1.50 hot dog combo on your way out or picking up a whole pepperoni pizza for the family, it’s the best "reward" for navigating the aisles. There’s a good amount of outdoor seating where you can actually sit down and eat without feeling rushed. It’s the kind of place where the employees are genuinely fast and the "treasure hunt" for new items in the center aisles makes every visit feel like a little bit of an adventure.

Be aware shoppers do not shop at Gateway Costco.

- Gateway Costco is lacking customer service, leadership, and accountability
- Costco Employees at the Return Counter display bad attitudes
- Unprofessional asset protection employees

Gateway Costco (650 Gateway location) employees appear to have a breakdown in customer service leadership and accountability. In comparison to other locations (Costco Morena Blvd) this location is known for bad customer service.

During multiple interactions at Membership/Returns, staff including Diana, Mark, Nayali (or Natalie), and Brenda all demonstrated dismissive and unprofessional conduct over numerous interactions. Costco employees have been observed with unacceptable behaviors, including rude conduct and eye-rolling, visible irritation, and redirecting legitimate questions back to the customer rather than providing clarification or assistance.

It is with deep concern the Return department has conveyed negative experiences and unnecessary stress to many shoppers. This invites the competition of Online Shopping, i.,e AMAZON (hassle free returns at UPS), Walmart (90 day return policy), Target (90 day return policy), Nordstrom (no return window), REI (1 year return policy) to be Customer Service oriented WITHOUT HASSLE and lends more efficiency less interaction with unprofessional staff at Costco.

Asset Protection staff also presented in a manner that felt confrontational and unnecessarily intimidating during my shopping experience.

Pharmacy is lacking as well, as the Pharmacy Techs and Pharmacist don't like their job. They aren't happy when they answer the phones and I am not confident they would go the extra mile for their customer. When compared to H-Street Costco pharmacy, this Gateway location is below par in customer service.

The pattern is not a single bad interaction but a consistent tone of defensiveness and visible disdain toward customers. This reflects a lack of oversight and service standards at this location.

* NOTE: Corporate oversight may want to review training and leadership accountability at this warehouse. *

I went into Costco yesterday, to ask for help regarding my rewards certificate. I talked to an employee named Michael, he was wearing a red vest. He was so patient and very helpful. Thank you Michael!

This Costco does a great job of serving the local community by offering some ethnic foods not found at most Costco locations. Gas is more often than not the cheapest of the surrounding area Costco stores (unless you want to make a trip to Santee). Pharmacy is staffed by friendly and helpful techs who serve their customers like patients, with care and kindness.

If you haven’t been to a Costco business center, you have to stop here. Savings beyond believe.

Best to go during the weekdays to fill up. In the mornings around 8am. You can get through the line pretty quick.

This is the ghetto Costco,. Very low end products. Barely any organic food. I thought La Mesa Costco sucked, but this one takes the cake!

I love this Costco overall but the food court is run terribly. Why make kiosks only to penalize customers who use them with horribly slow service? I will never use the kiosk again.

Started with the optical shop, where I was helped by a very nice young lady & ordered new glasses. Then, I picked a few necessities and checked out. Very busy store, but everything moved along quickly.

Great Costco location! Gas prices are usually $0.5 cheaper than at the nearby gas stations. Also sells a ton of great things, including great sushi. It is busy almost all the time, and there is almost always a line for the gas. But it is worth the wait. It is more chill than other Costcos in San Diego.

A very ghetto Costco with Ghetto staff!!
2 of the check out staff were blatantly arrogant and almost racist to me and my family. We are people of colour and the 2 girls were also Latino but looked down and spoke down to people of colour as we witnessed. A white guy in front of us got the 5 star treatment and our trolley cart. The girls then didn't want to give our cart back to us as there was none left so I stood my ground and made them get me a cart for all my purchases. These nasty girls carried on serving customers until I made it awkward for them The girls were stupid and uneducated enough to think no one knew the games they were playing....BEWARE of these pretentious idiots and give them a taste of their own medicine!
