IPO watch: Restaurant stocks show well on day one, who's next?

|By:, SA News Editor

The red-hot IPO launches of Noodles (NDLS) and Potbelly (PBPB) have restaurant analysts buzzing over which chain might test the public waters next.

Cynics say the recipe of small float and lots of hype mask the real long-term potential for the new stocks.

Chains to watch: Chic-Fil-A, Subway, P.F. Chang's (again), Five Guys, In-N-Out Burger.
