I have an upcoming business trip to Miami. On these trips I usually eat at inexpensive local places but top it off with a splurge dinner the last night. Can you all give me some suggestions for both ends? I mean, the lower-cost but lip-smackin' local fare (Cuban and Conch included) and one fabulous place to top it off. Oceanside dining particulalry appreciated, as well as funky bar suggestions. Oh, I'm staying at the Lowe's Miami Beach hotel in South Beach.
