I went here for dinner on a Friday night with a large group of over 20 people. They don't take reservations and don't really have any large tables but the staff still did a wonderful job accommodating our group. They had to split us up but they were still very friendly and didn't seem as frazzled by our large group request as others have been in the past. The atmosphere is nice and open and clean. Sometimes in bar heavy areas, it's easy to neglect the food but not so here. This is more restaurant than bar. It looks like the type of place that would have burgers but it's actually Cajun. I wasn't expecting a good dinner but my Shrimp Po Boy was really good. The shrimp was fried just right and the sauce was great. Be warned, the fries are really spicy (I guess coming from the Cajun influence). The menu might say they're spicy but I wasn't paying attention, I assumed they'd be standard bar fries. Overall, it was a good experience and I was pleasantly surprised by the food.
Calypso is great. They have a menu with plenty of options, you don't have to wait long for your order, and the servers are happy to help you. They have plenty of locations around Nashville, but I especially like the Charlotte Ave location. I can stop by for a quick lunch with coworkers and enjoy great food.
I absolutely love their patio! On mild evenings it's a great place to enjoy a glass of wine. The service is always great. However the food is not consistently good. There's some nights I've been that the food was wonderful and then a few where it was just ok.
