2 things about Allen's should bring you here: Their abundant beer selection and out/indoor patio. We came here at around 10 on a Wednesday. The place was not too packed and we grabbed a seat on the back patio.
Along the back side wall, they have 4 blackboards with about 80 beers, organized by their type and region. The patio is pretty cool because the ground is covered in hardwood and naturally hundred year old elm trees sprout in the middle of it. During the daytime this patio would probably be great because of the natural tree shade, however during the night I feel that their lights are too bright and should be much dimmer.
Only 2.5 stars because the service is pretty slow. We had to flag down a server every time we need a refill and I saw a couple other tables being frustrated for the same reason.
Edit: I came here a 2nd time and the service was still slow and they forgot stuff or to comeback multiple times. I also had a chance to order some food. I have no idea why I paid $17.99 for a plate of Chicken Curry , but I did it anyway. It was alright, and had a good mix of spices, but did not justify it being that expensive. Glass of cider and chicken curry should not come up to over $35 after tip.
