impeccable service, stunning location. i recently had lunch here with my family. everything about the meal was at the highest standards. food was delicious, highly refined and perhaps slightly less adventurous that i might have expected. it is well worth a visit for the lunch prix fixe. my only complaint with the restaurant would be that they have an arguably antiquated practice of using 'ladies menus' which omit prices. because of this half of our large party decided to order a la carte having no idea that just the appetizer on the a la carte menu cost considerably more than the entire prix fixe lunch. a choice that would not have been made had it not been for the 'ladies menu' and polite gentlemen at the table who did not point out the cost discrepancy assuming all menus were the same. needless to say we ended up with a bit of a bad taste in the mouth when my mother (who was treating us to lunch) discovered her meal cost well over 1000 qar while for equally exquisite food the prix fixe was 200 qar per person.
we were also quite astounded by the treats delivered at the end of the meal. there was an embarrassing abundance of gorgeous chocolates, pastries and sweets as a gift from the kitchen so make sure to save room for these.
in short, please don't hesitate to visit for lunch but do be aware of the menus.
on a side note, the food served in the cafe in the lobby of the museum is almost certainly from the idam kitchens and is better than most restaurants. from what i've sampled so far at the cafe, the food is certainly on par with what is served at idam.
