I can't believe this hasn't been reviewed yet! I love the Miller, and I don't think I'm the only one - since its always packed when I go there.
Even for lunch during the week you should make reservations in advance. I went without reservations and my small group got "stuck" on the patio. This turned out to be amazing - because their patio is awesome, and very, very large. It was also a beautiful day outside, which never hurts.
The Miller Tavern might have served me the best food I've ever tasted in my life. I know, it sounds extreme but the menu is to die for. It is hard to make a decision because everything is so great. I don't know one person who hasn't absolutely loved their meal there.
I've been for dinner and lunch. Both times have excellent service, even though they were very busy. I hear the "Comfort Foods" section of the menu is the best - I ordered the Beef Tenderloin Cavatappi off of this once and it was amazing. The beef was cooked to pefection. They do specialize in seafood, complete with an oyster bar, but you can get all kinds of cuisines here. I've had dessert here as well, and was very impressed with the creme brulee.
They have a great selection of wine and a full bar. I love the atmosphere indoors, as well.
This place is great for dates or even company parties. I would recommend The Miller Tavern to anyone.
Lunch is about $20-30 and Dinner is more like $40-50 per person.
