Not going to lie, I choose to eat at E11even over all of the other restaurants in the city because I work in the same building. That being said, it is a decent dining experience.
The first time I went was for burger week in 2013. They had Nonna's Burger which was their amazing giant meatball appetizer on a soft bun with Parmesan cheese. This was one of only a couple "high end" burgers that chose to charge more than the five buck burger week price. This was not necessarily warranted since it was on par with other burgers on the list. Also, it was kind of a cop out since they already serve the meatballs. I feel the bun actually took away from the meatball and it would have been better on its own. Add on a side of $10 Truffled Parmesan Fries and you feel like you got ripped off.
My second experience was much better since it was just a nice lunch with my cousin. I ordered the Nova Scotia Lobster Roll and it was amazing. Lobster is stuffed into a soft buttered bun and sided with crispy frites and an appley coleslaw. Definitely worth the $27 because of the abundance of lobster - not sure I can say the same for my cousin's Tandoori Chicken Sandwich at $16.
Service at E11even is very good. Servers are polite and attentive in the way that you would expect them to be in a high end restaurant. My main concern with E11even is that it seems to be having an identity crisis. Is it a casual spot or is it a high end restaurant? The casual vibe comes from the menu of burgers, salads and sandwiches (even a hot dog). The noise level is loud and there are communal tables in the main dining room and couches on the patio. The high end feeling comes from the focus on customer service and the high prices!!
Basically, if you can overlook that you shelled out some coin for what most people would consider bar food, you will enjoy E11even.
