That's sad you could not visit. Yes the food is kind of Arabic Mezze, but there are a few Omani specialities also, the Omani halwa is one, its sweet. Khasab city we haven't yet got a chance to visit but it is on our to do list, hopefully soon. Oman is a very rustic place and you find a mix of everthing here, the sea, the mountains and some parts also are very lush green like Salalah.
