First of all I would HIGHLY recommend making a reservation before you go! It's completely worth it to call ahead.
The food is delicious! I had the L2 Cheeseburger which was one of the best burgers I have ever had. Their fries (frittes) are delicious, but their homemade ketchip and garlic aioli as a paired dipping sauce for the fries is oustanding!
We had reservations for 7 and the people at our table before us hung out for a bit so we didn't ge sat until 7:25. We were fine, but the manager sent out an appetizer plate to make up for the delay. Great service!
The waitress was fantastic. She took care of us well, but didn't hang out too much. The atmosphere is great too!
