A few weeks ago I was lucky enough to be invited to go and have lunch at the new Lebanese restaurant at the MGM, Semsom. I say lucky enough because I got to taste so many different things on their menu, so much so that I needed a nap afterwards (but didn't cos I had to work!) and it was all really tasty stuff!
I'm not really a food critique, but if you are into food reviews, you could check out Foodishly in Love's review of Semsom here, or if you prefer you could read FatSu's thoughts on Semsom here, or even Badermania's thoughts here.
I'll short cut it all for you though: Semsom is a very good restaurant, and certainly well worth a visit.
I enjoyed pretty much everything that was put out for us to try, but the one thing that has stuck with me the most is this amazing drink they made, which when I read the menu I thought.. gross no way, but I was told I had to try it, and I'm glad I did. The drink is called Jullab, and it's a rosewater date drink with pistachios and something else. It's really tasty - I highly recommend it.
The lights in the restaurant are fun, they have a spoon melded into them which houses the light bulb - very fancy. The décor is nice and fresh too, and the price-range is comparable to the rest of the restaurants at the MGM. EG, a dinner for 2 with some juices will be under 20 rials unless you're super hungry and order loads and loads of food.
Seriously though, go try Semsom, if only to check out the pink hummous (I recommend you add the table oil to it) with the hot bread buns and the Jullab drink. Lush.
