Five rooms. Four days. No cover at any of them.

Two of the five publish what the food costs.

Tonight is one room and it is Colonial Oak Music Park, 27 St. George Street, and the first set is at 4:30. Four rounds, back to back, finishing at 9:15.

The Oak’s own page says the park is open daily 11 a.m. to 9 p.m.

Nine is what they wrote down. The last set is booked to 9:15. Plan on the music, not the sign.

There is a full bar and no food menu on that page at all, so I cannot tell you what a drink there costs. Nobody has published it.

Twelve dollars is the rule on this beat.

Where the prices actually are

DJ’s Clam Shack, 21 Hypolita Street. One block off St. George. Open Tuesday through Sunday, 11 a.m. to 9 p.m. They play the festival Friday and Saturday from noon.

This is the one room in the five that prints a full price list where you can see it, and eight things on it come in under twelve.

Cole slaw, $3. Garlic bread, $4. French fries, $5. Sweet potato fries, $7. Onion rings, $8. New England clam chowder, $9. Split grilled beef hot dog, $10. Key West salad, $10.

Above the rule it moves fast. Cheesesteak $14. Chicken fingers, conch fritters and the garlic steamed clams all $15. The shrimp poboy, the oyster poboy, the clam strips and the fried shrimp are $18 each. Coconut shrimp $19. The Ipswich fried clams are $38, and the lobster rolls are market price, which is not a price.

One thing in their favor that most places do not do: the fried plates and the grill plates come with fries or slaw already. So $18 is a plate, not an entree with a $5 side bolted on.

Their footnote, word for word: “All prices subject to change without notice. Prices will vary per location due to market conditions.”

Prohibition Kitchen, 119 St. George Street. Friday and Saturday, 11:05 in the morning.

Their food menu page lists every dish with a paragraph under it and not one number. The prices are in a PDF the same page hands you, filed under August of this year.

Under twelve in there: boiled peanuts $7, skin-on fries $7, a premium side $7, pork rinds $8, a root beer float $8, a milkshake $9 without alcohol, brussel sprouts $10, fried pickles $12.

That is the whole under-twelve list at a gastropub. Everything else starts at $14 and the burgers are $19 and $20. The milkshake with alcohol in it is $13, which is four dollars for the alcohol.

Tradewinds Lounge, 124 Charlotte Street. The only two sets in this festival that start after ten are here, Friday and Saturday, 9:15 and 10:30.

No menu on the site. No prices. No posted hours. The September calendar is a picture you hover over to zoom.

Boat Drinks, 123 San Marco Avenue. Sunday, 11 to 3, and that is the last of the festival.

The menus page loads three items. Smoked fish dip, $17. Blackened fish sandwich, $MKT. Raw oysters, $MKT.

That is the entire published price list for a raw bar, and two thirds of it says market.

If you are not going downtown

Milltop Tavern has Joe Downing from noon to 4 and Jon Q Duo from 4:30 to 8:30 tonight. Also free, also no cover, also nothing published about what anything costs.

The order

Get to the Oak by 4:20 for the 4:30. The music is free and stays free until Sunday afternoon.

Eat first, at DJ’s, one block over on Hypolita. Chowder $9 and a hot dog $10 is nineteen dollars for two people before tax, and both of those are under the rule on their own.

If the line is long, the Key West salad is $10 and the onion rings are $8.

If you would rather eat after, DJ’s closes at 9 and so, on paper, does the Oak.
