I am sorry, but this is such a one sided hit piece. The glowing review of the food and the people without ever going there to eat I am sure.

The lease was not renewed. The land lord has a right to do that. Unless they break the terms of the lease with the tenant I do not see how there is a case.

If the food and service were so great, take the business to another location. I am sure you would be able to repeat the business model. Build your own shop? Until you own the property, you are going to be subject to rent increases and possibly not having your lease renewed. Maybe they should have asked for a longer lease, but I am sure they were afraid of being locked in if the business failed.
