I think Sweets & Savories food is wonderful, but the last time we were there, the service was very rushed. We had a 9pm reservation for 4 people on a Saturday night. We ordered several appetizers to share and we were not even done with them when our entrees appeared. We were in our car before 10:30 and dinner is rarely under a two hour event with my family. Again, the food was fabulous and the prices are extremely reasonable for the quality...I just don't know if it will have the "special occasion" atmosphere that you are seeking.
Last year, to celebrate my doctoral defense, my family and a few friends ( I think there were 12 of us) went to One SixtyBlue and loved it. I think the atmosphere and service will give you that special occasion feel, the food is spectacular (although I believe that the chef has changed since I have been there) and the prices are "reasonable" compared to the absolutely top restaurants in the city.
Congrats on your upcoming graduation from med school!
