We went to District oven in the context of Winterlicious.
The food was amazing. and portion sizes were adequate. On the basis of that you should definitely give the place a try.
However, the service left a lot to be desired.... so much so that even the table next to us were complaining. We came into an empty restaurant to a confused hostess who did not know where to seat us.
Once we were seated, we ordered our meals. When the same two appetizers came (dips and sauces), we had one piece of bread for the two appetizers. Every other table had two breads for two appetizers. We kindly asked the waitress... three times in the span of 30 minutes. No acknowledgement. It should not be that difficult to get a piece of bread. Waitress could not care less about our table. While taking our order she spoke over us to the table across, which was pretty rude.
Food took a while to come out, and the general consensus was that there were too few waiters/waitresses for the amount of people.
