My nephew and his wife are coming up next Friday night with their two boys, age 2 and 4. We would like to take them out for dinner somewhere but I need some ideas as to what the kids might find fun (not boring). They want to do the Pike Place Market (of course) so we will be there at some point Friday afternoon/evening or Saturday day and I know the waterfront is close by also. It would be Friday dinner or Saturday lunch. Also we live in the Renton area so ideas for Renton, Issaquah or Bellevue would be great. It doesn't need to be fancy, just fun and not a chain (like Red Robin) as they have probably been to it.
We don't have kids ourselves so I am relying on you ChowHounds to help!
Thanks in advance!
