A cute theme today where cities replace words in familiar two-word phrases and are clued in a way that forces them to make sense. As in, "Ways to cross a river in Switzerland?" BERNBRIDGES, and "First showing at a film festival in France?" CANNESOPENER. Ha!
On the non-enhancement side, I would include the BABU/BABA pair. The first is, I grant, interesting trivia, and the second, while it may be tasty, has the slight off-taste of crosswordese. IMUS and TWOTERM have an unpleasant "politics" vibe, and the inclusion of four (!) additional cities - GENEVA, AGRA, CAEN, and SOCHI - seems a little unfortunate in a theme focused, as it is, on cities. Add to that a DAB of PHON, REV, GTE, ESE, and LYIN, and you've got a valid BEEF.
IMHO, however, the amusing theme wins out today. PRETTY solid debut puzzle, and I'll be looking forward to more from Mr. Mintz.
