I'm assuming this space is to rate Chartreuse French Restaurant since there is no restaurant specifically called "Signatures" on board the Mariner. Chartreuse French Restaurant That evening I had scored an early reservation (it was the best I could do) at one of the Regent Signature Restaurants, Chartreuse a French Restaurant. I was excited to try what Regent called "Modern French Cuisine". While the dining room was well appointed and comfortable the initial service, and later the food, were a disappointment. We were the first in the restaurant (right at our appointed time) and service was, for lack of a better word.... inattentive. For being the first customers (read ONLY Customers) it took a while to be noticed and seated. The sommelier was slow in visiting the lone table we were occupying . Then the sommelier immediately tried to up-sell me to a $275 bottle of wine and it took me just a moment to catch on. I did ask him what the featured wines were that evening and he recited them showing them to me on the wine list. Regent advertises as an "all-inclusive" cruise and indeed they are. Two wines were included that night, as in every night, a red and a white. But.... If I had not noticed the tiny prices following some of the selections I would have purchased a $125 to $300 bottle of wine. When I quizzed him about the menu he reluctantly confirmed that there was indeed an "upcharge" for those particular premium selections. I told the sommelier please just bring the "house red" after I was clued into the rules. He was visibly disappointed at the lack of the sale :-) The waiter came to the table immediately after the sommelier vacated and told us of that evenings chef's special choices then left us to peruse the menu. He returned after an appropriate amount of time and left with our order. For appetizers my wife ordered Escargot and I ordered the seared Duck Foie Gras. Entrees were roasted lobster for her and double cut Lamb ribs for me. The Escargot were terrible. Served in a disgusting gravy of some sort they were rubbery and served removed from the shells, a good indication they were (possibly) frozen or even (GASP!) from a can. My Foie Gras was somewhat better. It was nicely displayed/presented with three little apricot dots arranged on the plate. Taste was meh... rather tasteless and bland. The entrees didn't fare any better. My wife's entree, Roasted Lobster with Scallop Mousseline, Green Asparagus and Fava Beans, was displayed well but was extremely overcooked resulting in a tough, tasteless piece of unrecognizable meat. The vegetables were fine and well cooked. My lamb was delivered beautifully presented and flanked by two Chickpea Fritters. However I had ordered the lamb Medium RARE. It arrived terribly overcooked and tough. As a result of this criminal treatment of what was likely a decent piece of meat it was largely tasteless and tough. My desert, Creme Brûlée was well presented and was tasty, rich and creamy with a satisfying sweet/bitter crunch from the caramelized sugar on top while the wife's Chocolate Napoleon was inedible.
