I wasn't sure what to expect because a lot of the reviews were pretty lackluster. Overall I have to say I was pleasantly surprised by my experience:
Service- Luis ( I believe was his name) was a soft-spoken man who needed a little lesson in confidence but overall was kind and did an ok job. He brought me a sample of wine which was nice, though I had to ask for the wine list, and we had some pacing issues with the service.
Atmosphere- Very casual and a bit outdated...you could easily tell it was a Holiday Inn restaurant. We walked in and noticed it was smoky (something burned earlier) and they had all the doors open so combined with the open kitchen area it was a bit stuffy/hot in there.
Food- I enjoyed my tuna appetizer and my filet was absolutely delicious as it was seasoned and cooked perfectly..The dessert was a disappointment, a COLD nutella crepe lacking gooeyness...boo.
The pacing of the meal was off, we arrived at 8pm to a fairly empty restaurant and we did not leave until almost 10. I know some meals take a couple hours, but we sat breadless (though the bread was delicious when it arrived) for the first half hour and our dessert sat on the table for a bit. Food took a long time to prepare - we noticed this from the open kitchen
Caffe Siena earns a solid 3.5 (the food being the primary star earner in this case). Since food trumps all, I'd be glad to return here.
