The Side Door is a nice reliable pub with tasty food and reasonable prices. Get the tots!
We've gone here numerous times with Groupons and simply because "it's next door." It's about 1 block from our apartment and it's awesome to have a simple gastropub with a variety of apps, beer, and burgers.
On the most recent visit, I tried the Surly fish fry. It was awesome! Huge portions with crispy fish. I got tots as my side instead of fries, and it was such a good choice. Just listen to the people and try the tots. They are huge and so much better than the frozen things. I will say that I'm a little disappointed they changed the name from "Tot-chos" to "South of the Border Tots." Those are my favorite by far: cheese, guac, and other nacho toppings on top of tots.
I also opted for some white wine since we were sitting outside and it was a warm summer evening. SD has a bunch of $5 beers and the rest of the drinks are equally reasonably priced.
Can't wait to come back next time we need a quick dinner or can't decide where to go!
