I went here for dessert recently on a Saturday evening. The ambiance is o.k. I would expect them to put a little more effort into it since this is a romantic dessert-centered restaurant. Several of the items that were no longer available to order were scribbled out. We ordered Silent Swisses and Irish coffee type drinks. These drinks were good; we also ordered desserts: the New York cheesecake was a generous slice and delicious and the profiteroles were good, not amazing, I think something  added to the dish would have made it pop. The waiter was attentive, but a smile would have helped.
Review Source:I had never been to Allgos but heard about it from a bunch of people. The reviews were mixed but with a Groupon I decided to give it a try for dessert after a great meal and drinks at Baba Sushi.
Not knowing where on Shrewsbury Street is was my eyes were peeled as I looked. I almost drove right by it since from the outside it looked closed. It was dark and not particularly inviting.
When we walked in I immediately felt out of place. It is clearly more Guido bar then it is Dessert Lounge. The bar was clearly popular but the rest of the dining area looked like a mess of tables not laid out well. There were tables right on top of each other with no room to move a chair and in the corner a big spot where there where no tables.
We ordered a Latte and a cappuccino while we decided over the list of options for dessert.. We choose the Peanut Butter Cheesecake and also decided to try the sampler which had slivers of the Hazelnut Cake, Limonchello Raspberry Cake, NY Style Cheesecake and the Coconut Cake.
Sadly both of us couldn't find much worth having here for desserts and coffee. Both coffee's tasted burnt and the desserts were clearly not fresh. All of it had that open box not touched in a while refrigerator taste.
The bar scene looked popular and the drinks looked good so I think they realized that they would be successful as a bar and not really a dessert shop and really let that portion of their business suffer. I rated it based on dessert's and coffee not drinks. They might have rated higher if I had a cocktail
