1. Caskhouse Opens: Noe Valley beer fans now have a bar of their very own; Caskhouse (which was supposed to be called Crafthouse, but got a name change after Tom Colicchio of Craft sent a cease-and-desist letter) is now open, with six California draft beers ($7 a pint) like CaliCraft Cali Kolsch, Ballast Point Sculpin IPA, and Drake's Robusto Porter, as well as several wines by the glass ($10-12) and a handful of bottled and canned brews. Hearty food offerings include housemade salt and pepper chips ($4) and porter-braised beef short ribs ($8). (Tuesday-Friday, 4 pm-12 am and Saturday-Sunday, 2 pm-12 am; 3853 24th St., Noe Valley.) 

2. Caña Opens: Also new this week is the second location of Oakland Cuban stalwart Caña in the former Circolo space in the Mission. Caña specializes in classic dishes like black bean soup, fried chicken, plantains, and of course, Cuban sandwiches. But drinkers should also take note of the cocktails, with offerings like the Some Like It Hot (reposado tequila, serrano chile, lime) and the Chango's Sword (rum, lime, Licor 43, basil oil, brandied cherries). (500 Florida St., Mission.) 

3. Happy Hour at Mission Street Oyster Bar: This seafood spot in the Mission is also a relative newcomer, and if you have yet to try it out, consider stopping by for their killer happy hour, which features $1 oysters and $2.50 beers until 6 pm. As the evening wears on, you'll find hearty seafood fare like clam chowder, fried calamari, fish and chips, and dungeness crab cakes, not to mention plenty of bivalves-- chef Fredy Gamez worked at Anchor Oyster Bar in the Castro for nearly two decades. (Daily, 3-10 pm; happy hour 3-6 pm, 2282 Mission St., Mission.) 

4. Michael Mina/Beretta/Delarosa Bar Swap: Two of the city's best restaurant cocktail programs are mixing it up for two days next week: Michael Mina bar star Carlo Splendorini will head to Beretta on Tuesday and its sister spot Delarosa on Monday, while Beretta bar manager Dominic Alling will take over his spot at the bar at Michael Mina for both days. Splendorini's special drinks will include the Lavanda (vodka, Lillet blanc, lemon, absinthe) and the Company (saffron-infused gin, lemon, honey, orange-blossom water, thyme), while Alling will mix up drinks like the First Peak (gin, lemon, saba, peppercorn tincture) and the Queen Anne's revenge (rhum agricole, sweet vermouth, Campari, creme de cacao). (Alling: Monday-Tuesday, 5-11 pm, at Michael Mina, 252 California St., Financial District. Splendorini: Monday, 6 pm-1 am, at Delarosa, 2175 Chestnut St., Marina; Tuesday, 6 pm-1 am, at Beretta, 1199 Valencia St., Mission.) 

5. Guinness Believer Beer Tastings: If you've been known to enjoy a Guinness or two, you won't want to miss the famed Irish brewery's special events in SF next week. In exchange for a $5 donation to the SF Fire Department, they'll give you a free pint of the good stuff, as well as samples of the other beers in their portfolio, like their black lager and foreign extra stout. Though this event isn't happening until next week, reservations will likely book up by then, so we wanted to get the word out now. RSVP here. (Wednesday, January 30-Friday, February 1, 6:30 or 8 pm, at Terra Gallery, 511 Harrison St., SOMA.) 

After three years of scroogin' for a boozin', I'm sad to say that this is my last drink column for 7x7. Starting next week, I'll be the new editor of Eater SF. Thanks so much for reading, and please drop by Eater to say hi! --Allie Pape
