I absolutely love this Jimmy John's location. As a UNLV student I usually frequent this location on my way to work and pick up my sub to go. The lunch crew is always on their A game, energized and friendly. You're acknowledged the second you open the door and they're ready and waiting for your order which will be prepared in less than a minute usually. They recognize their regulars as well. I hadn't been in for a few months over summer and I recently came in and they still remembered my order. Great customer service! And of course the food is delicious. My favorites are #16 with Dijon and you can't go wrong with the #9. Sandwiches are always fresh, delicious, simple and tasty.
Now if you're going at night it's a COMPLETELY different story (hence the 1 star deduction). I used to come here at night before my night classes but I have stopped doing that. First of all, it's always been pretty empty when I've gone at night so you'd think there would be awesome customer service...wrong. The few times I went at night you have to wait a few minutes to even be acknowledged while the staff continues their conversation (whether it's with their fellow coworkers or their friends who are there eating). Eventually they take your order and make your sandwich at a glacial pace. The entire time you're there you feel like you're inconveniencing them and interrupting their evening.
Needless to say I've found a different place to eat before my night classes now. But if you're around in the day you absolutely need to come by!
