You may see that on many of my recommended restos I've placed a [PROVISIONAL] note. This refers to the fact that I've been there only ONCE and even though I liked it, ate safely, talked with the owner/manager/chef, still it's only been tested by me ONCE.
Most restaurants I will frequent multiple times before I write them up. However, sometimes I've had such a great, welcoming experience the first time that I want to make sure you all know about it.
Especially with these provisional restaurants, PLEASE check with the restaurant first before going as chefs change, so do menus, owners, managers and attitudes towards the special request diner.
