Le Mardi Gras is a pretty cool place. VERY different from the rest of the bars on Walnut. The atmosphere has a very lax and divey feel so this is a good place to go if you want a chill night.
The drinks are on the expensive side but they are extremely strong, definitely a one-and-done bar!
The only downside to this place is that it is pretty smoky if you are a non-smoker. Otherwise, Mardi Gras is a pretty sweet if you want a quieter night out and are looking for strong, yet tasty drinks!
