Oh, and I want a big corner booth.
Okay, just one moment while I check the availability.
Okay, take your time.
I'm sorry but the booth is not available. Can I check tables?
Yes, tables are okay if booth is not available.
Oh, so sorry, but unfortunately they do not have a table that's large enough for 6.
Oh...well, then how about Sonobana restaurant?
Let me check.
Okay, hopefully they have a table or a booth.
They do have a table in the private area that will accommodate 6.
Sounds good. That will be fine.
