Went to the Sultan restaurant today with family visitors.
Plus points:
Good food, friendly staff, clean loo, although there is only one for both ladies and gents.
Waiter speaks English, not too expensive, 15 euros each including a couple of beers.

Minus points:
Decor a bit too bright, chairs very basic and a bit uncomfortable after a while, "Bollywood" dance music on all the time.

But if you miss Indian food, well worth a visit.
