Assa has a wonderful view on the river Loire but the view is not the most important part of your experience in Assa.
We were a couple with a kid and went for the 5 courses menu, with for our 6 years old kid, a simple course with dessert. I won't describe what we ate as the menu is surprise. If you are concerned about the surprise, the waiter gives you a paper with the menu description. You can have a look at it before ordering or let the surprise catch you.
Flavours were numerous, surprising and mainly delicious.
Service was attentive but discrete and professional.
The chef presents at least one course to each table.
Compared to one star restaurants we have in Belgium, the value for the quality was very fair. We ended up with a 248 euros bills for two 5 courses menu, one meal and dessert four our daughter, juice, water and a bottle of wine.
We will definitively go to Assa again if we go back to Blois!
