We were in town for a weekend away and our hotel book the reservation. This place was amazing from the moment we sat at the bar to the time we waddled out of the joint 2 hours later.
The bar: Classic, perfectly lit, bartender was about as good as it gets (and I can't remember his name). We had a great bottle of white (Italian) with our friends and chatted with the bartender about dinner suggestions. Was pleased that of all the items on the menu he actually walked us through many, he asked us questions about what we like and steered us appropriately.
Getting to the food: It was the first week of October and we chose to sit outside....ahhh, perfect. The only hiccup of our entire experience came when 10 minutes after seating us we still hadn't been approached by a server. We flagged the hostess (What's the right way to call the person who greets you, seats you and is one of the owners?) and she couldn't stop apologizing. What was great was that instead of sticking one of the waiters on us, she saw how much fun we had at the bar and had the bartender act as our server as well.
Food: Needless to say we all were guided to wonderful dinner choices. I can honestly say that this was the absolute best pasta-centric meal I've ever eaten. Mine had 1/2 a lobster, an amazing sauce and other goodness in it. Is it possible for pasta to melt in your mouth? Mine did. The other 3 at the table had the same experience. We also had a wonderful tour of Italy via the wine that was paired with things. Dessert was amazing as well.
Marcellino had the quaintness of a family owned place combined with the experience and food quality of a fine restaurant. I cannot say enough about the quality of the food and the service. If you have the chance, go there!
