“Anthony Bourdain: No Reservations” (9 p.m., Travel) celebrates its 100th episode with a return to Paris. Let’s hope it’s better than the 99th. Long an admirer of this show and its host’s acerbic and occasionally cerebral take on food and culture, I can’t help but feel that “Reservations” is running out of gas.

Bourdain’s recent trip to Rome (his first) seemed a little more about indulging the host’s Fellini obsession than the Eternal City’s culinary delights. A recent episode offered a 10-year-old film about Bourdain’s first book tour. And last week, a return to India was presented as a “Making of” episode filled with inside-baseball stuff.

It was nice of Bourdain to put his crew on camera and it must have been interesting to somebody, but as a show it was a snooze. To paraphrase Bourdain, I was left hungry for more, but certainly not that.

With the 100th behind them I hope the host and producers of “Reservations” start thinking about their audience again and stop making self-indulgent home movies.
