i'm a big fan of firefly I love the food, the cocktails, and the atmosphere. The food here is tapas style so small plates. The prices per plate run from $5 to about $10 dollars each with a few larger priced entrees such as the paella. Their also known for their sangria and I personally recommend the sparkling sangria over the other two.
The atmosphere here would be considered trendy and tends to be on the loud side but as long as you know that going in its no problem. If you go on a friday or saturday night expect service to be a little bit less than stellar because of the sheer number of people in the joint. Some of their stand out dishes would be the bacon wrapped dates, the ham and cheese croquetas and the manchego mac & cheese.
