Overall, a decent modern pub. Was surprised by the DIY pours for beer, but actually warned up to it after a couple of drafts (there may be some underlying connection there). Really enjoyed the Third Wheel Sandman red ale, notes of cherry seem to come through after a swallow; really refreshing on a hot summer day.

First time here and everything was excellent! I got the honey bourbon chicken wings with onion rings the sauce on the wings was so good the chicken was fried perfect the onion rings was big and juicy and you can taste like the batter had beer in it!!! Our waiter Mr Andrew was fantastic! Very nice young man when you visit please ask for him!!!

It was a disappointing experience until the food arrived. But let's break it down.

Food: It was delicious. We ordered burgers, wings, and tater tots. The wings were solid, the burgers were delicious, and the tots were crunchy with proper seasoning. I personally got the burger and it pulled this rating from an overall 3 star to a 4 star. It was fresh, juicy, and well portioned.

Service: I've seen too many mentions in their reviews...
