I never had a better Falafel. That's it, basically. Oh and have the Falafel with Eggplant, they also have the best baba ghanoush I ever had! Even though the hummus is very good, too.
In a few months I'll try the L’As du Fallafel in Paris which is said to be the best Falafel in Europe. So perhaps I'll change the review to "Best Falafel in Europe" afterwards ;) Or I'll have a REALLY incredible Falafel in Paris!
Update: The Falafel in Paris was very good, but the main part (the Falafel balls) couldn't beat the one from Aroma. So it's officially the best Falafel I ever had in Europe!Pros: Excellent food, Best Falafel, Good Value
Cons: Very popular means long waiting time, No real seating, Also offer meat and cheese
