We picked rather an unfortunate evening to go here. We went with another couple and had a good table in the window, but there was a rather loud large group of people in here as well. Perhaps this is why the service was not particularly great. We were surprised when we sat down at our table and no one offered to take our coats, and then the service was fairly slow - but perhaps to be expected due to the number of people in that evening.
The Dining Room has not been open that long, under a year at the time of writing this. The food is tasty and there is a good choice on the menu. All the same we were disappointed by the lack of vegetables on the plates.
Although not perfect, The Dining room has potential, and once it has got through it's teething probems I am sure that it will be a good restaurant to add to your list of places to go in Ipswich.
