Tim Love and Joe Bastianich as seen in “Restaurant Startup”

Sometimes, you can have the greatest, the most original and the most exciting business idea in the world. The trick, though, is finding the cold, hard cash to turn that idea into reality.

That's the premise behind ABC's huge hit "Shark Tank," in which small business owners and entrepreneurs pitch their ideas to a panel of wealthy investors, hoping to secure enough cash to take their dreams up to the big leagues.

It's also the premise behind "Restaurant Startup." Its first season was a refreshing change in the culinary TV landscape, and with its second season premiering Tuesday, Jan. 13, on CNBC, a lot more restaurant entrepreneurs are about to become very happy.

Each episode of "Restaurant Startup" finds two teams pitching their restaurant concepts to a pair of investors, hoping to score the cash to start up their businesses. These investors aren't just two wealthy guys with money to blow, though; they know the restaurant business inside and out, and they're sure not going to be giving their moolah to businesses that they don't believe in.

And just who are these investors? Well, Joe Bastianich probably won't need much of an introduction. The successful restaurateur has been a fixture in "MasterChef" and "MasterChef Junior" from the very beginning, and fans of those shows know that he's a tough critic to please.

At his side in "Restaurant Startup" is Texas chef Tim Love. The owner of several restaurants, he's no stranger to the TV spotlight, either: he's been a frequent guest on ABC's "Good Morning America" and NBC's "Today Show."

With a pair of teams each pitching their restaurant concept in each episode, Bastianich and Love need a way to determine which idea is truly worth their investment. What better way to find that out than with a proof of concept? Following their pitch, each business team is handed $7,500 and given 36 hours to launch a pop-up restaurant in Los Angeles.

They won't just be cooking up food during this test period. They'll need to come up with a full business plan and a branding campaign before finally opening their doors and serving hungry diners who are always more than happy to give feedback -- both good and bad.

In the end, though, it's up to the wealthy investors to decide who has the better concept for a restaurant. Like any investors, they're ultimately in it for profit, which means that only one of the teams will win the cash infusion it needs to make its dream a reality.

Season 2 of "Restaurant Startup" premieres Tuesday, Jan. 13, on CNBC.
