I would definitely travel across London to eat at Joannas. It is probably the nicest restaurant I have ever been to. I have eaten at Joannas three times now and was completely satisfied with the impressive service, delicious food and reasonable prices. If you love you food you must try this restaurant.

Joanna's is a nice restaurant but I wouldn't have thought it was worth venturing across London for. Joanna's is probably best left to the locals who seem to love it as it's always packed.
