From classic Japanese dishes to unique plates from obscure countries like Eritrea, here are some of the most popular restaurants in London known for specializing in dishes from all over the world:

London's Le Mercury

When it come to finding the best French cuisine in London, nothing beats this Islington-based restaurant. And with starters costing around £5 and mains as low as £10, you don't even have to break the bank to get a mouthful of French cuisine during your visit to London.

Some of the many popular dishes include the French Poitrine de Porc, the Boulettes de Pomme de Terre (sauteed gnocchi with cream of butternut squash), the Filet de Loup de Mer (pan-fried bass fillet) and the Carpaccio de Boeuf (beef carpaccio, capers and red pepper relish). They also have a wide range of French desserts like the Apple Tarte Tatin or the White Chocolate and Mascarpone Cheese Cake.

Mosob Restaurant

If you've never heard of Eritrean cuisine before, then you are not alone.

Apparently this restaurant specializes in dishes originating from Eritrea, a country located in the Horn of Africa, and some of the many unique items they offer include Eritrean pancakes and Timtimo rolls (with rolled injera and lentil sauce) - but their vegetarian, chicken and beef sharing platters are considered to be the most popular dishes on the menu.

Bear in mind that the majority of the dishes are designed to be eaten with your hands, and each dish comes with a side of rolled up bread so you can soak up all the different Eritrean juices.

Cafe Chula

This Camden-based restaurant serves the best Mexican cuisine that London has to offer, and it all it takes is one visit to this gem before you find yourself returning to it again and again.

Not only do they have classic Mexican dishes like quesadillas, enchiladas, tacos and burritos, they also have a wide range unique drinks as well (like grapefruit or jalapeno and cucumber margaritas, mojitos, mimosas and much more).

The joint is perfectly situated in the heart of Camden so you can easily drop in after an exciting day of checking out the Camden Markets.

Koya

Koya has been coined as being the best Japanese-style restaurant in London; and although it may be a little pricey, if you're craving a little Japanese cuisine during your trip to London then this is the place to be.

Their udon noodles are made fresh on-site, and if you're lucky enough to find a seat near the bar, you can even watch the chefs work their magic on your dish.

The Buttered Baby Clam Udon, tempura starters, and small clams steamed in butter and sake are some of the many original Japanese menu items at this restaurant; but you can also find a few dishes with a slight British-twist as well.

Oh yeah, and there's sake. Lots of sake.
