Now that I've been to Commonwealth three times, I figured it was a good time to throw out some early thoughts.
Our first meal was a dinner on their first week. The sides were (and still are) comically overpriced at $9. On what planet ~10 potato wedges or a tiny cast iron pan of plain old roasted brussel sprouts is worth that is beyond me. The highlight of our meal was a spinach salad with a really great cheddar cheese. The mint chip ice cream was also very good.
Second meal was lunch. We shared the steak and cheese and brisket sandwiches. Both sandwiches felt like they were missing something to cut a little of the fat, but were still quite good.
Third meal was also lunch. We both had the pastrami sandwiches which were outrageously good. Served on marble rye with cole slaw and thousand island dressing. Also comes with fries and a side salad for $12. Really solid value at lunch. They were also cranking out the food quite quickly, so it totally works as a work lunch spot.
I recall six beers on draft (Jacks Abby, Night Shift, Dogfish Head, Stone, Weihenstephaner and Brooklyn) as well as a crafty bottle and can list.
Service at the bar has been very good. Some of the waiters are still a little raw, but that will most likely improve with time. We will definitely be back for that pastrami. Also excited to try their Sunday brunch. Not sure if we will do dinner again in the near future. Not crazy about the value proposition as compared to other places in the area. I haven't gotten to try any of the food in the market area beyond the ice cream, but they've done a really nice job stocking that space. Chef Nookie has also been there on each visit, and he's been working the line each time.
