This Demetre's location can get quite busy, especially on the Sunday night that I went. There is plenty of seating though, and the service speed is moderate. The inner decor has a diner type feel and relatively clean; great place to bring a bunch of friends to mingle and enjoy dessert.
Onto the food: the selection of desserts is quite vast but they all revolve around different combinations of ice cream + crepes / cakes / fruits-toppings and coffees. I had the "Tongue Depressor" which consists of a strange tasting flavour of ice cream, white/dark chocolate chips, fudge brownies, whipped cream, chocolate sauces topped with a large crepe. Other than the taste of the ice cream, everything else was to my liking.
If you decide to order the crepe or cake combinations, Either come with an empty stomach or share between two people because the portion size is quite large for a dessert; I did not finish even half of the plate.
