The newest restaurant at the Muscat Grand Mall is due to open next week on the 24th of June - Elevation Burger. The place was ready in February but staffing proved a bit of a challenge but now that's been overcome too.
I was fortunate enough to be invited to a secret tweetup at Elevation Burger earlier this week and I got to see and sample the wares - it was very good. The burgers are all made from Halal Australian grass-fed organic cows, and the burgers are made on site - they have a big grinder in the back. The fries are made from fresh potatoes and are cut right in the front and freshly fried in olive oil, a nice touch!
The pricing is not bad - its obviously more than the large fast food chains, but then again these burgers are a lot tastier too. I'm sure it'll be crazy-busy at first, but if you are hungry for a burger, its definitely worth trying out.
