It’s a convenience store but this area is not a good area. Staying in the hotel nearby and taking the pictures, there are a lot of people just hanging out but you can see in the pictures the Galveston Police staging in the parking lot. We even witnessed a woman using the restroom(squatting) behind their dumpster. Seems to be a popular place. Just go in, get what you need, and get out of the area. Not so nice at night.
