The merfolk settlement of Ucho Oyo is situated within a cove, in between steep limestone cliffs. It is a small village of wooden huts and various outbuildings, as well as several piers. A few fishing boats float lazily in the bay.
Most of the buildings appear to be private dwellings or used for storage, and only a few appear to be public. However, it doesn't take the three strangers long to happen upon what might be described as a dockside tavern.
The structure itself is rickety and unremarkable. Fishing nets are strung along the outside as if meant to be decorative. They can't make out much detail, as the sun has set some time ago, but torches have been setup along the pier, as well as periodically between the buildings to provide enough illumination for one to make their way around.
The inside is well lit by sconces, however you note that each flame is a different color: blue, purple, and turquoise. And it is under these otherworldly pastel tones that you see your first merfolk.
They are build like humans, except for the long fins that extend from the backs of their forearms and calves. They wear little clothing, apparently preferring to drape themselves in a minimum of cloth. Because of this you can see their fingers and toes are webbed. Hairlike growths spout from their heads, and is either thick and bristly like the needles of a sea urchin, or long and wavy, resembling fine seaweed. Some of the men have similar growths extending down from their cheekbones.

Perhaps to Liam's surprise (or perhaps not) there is a spattering of humans here as well.
No one in the tavern seems to pay you much heed, aside from noting your entrance. They huddle in small groups, drinking and chatting quietly. One group of merfolk stand off to one side, tossing darts at a wooden board with a crude painting of a reptilian creature with three rows of tusks jutting from it's upper jaw.
The barkeep, a large and heavily muscled merfolk and lacking any hair growths offers you a warm smile as you approach the bar. He produces two wooden mugs before asking, "What'll it be?"

Liam looks around to see how well-armed the various patrons are. It's partially to assess the danger, and partially to make sure he's not committing any kind of faux pas by bringing his own weapons to the tavern.

To the barkeep, he says, "Three ales, please." Hopefully ordering something bland and commonplace won't out him as a newcomer.

He keeps quiet, waiting for someone else to speak (or not), although he will make inconsequential talk with his own party if he thinks no one is eavesdropping.

A few of the others gathered here have daggers on their belts, but most appear to be more akin to fishing knives than actual weapons. However, no one seems to alarmed to see you and your companions armed as you are.
The barkeep's brow raises slightly as you order three ales. He pours a liquid into the two mugs he previously placed on the counter from a tap behind him, before producing a third. The containers are wooden, so it is hard to see the color of the drink inside, but there is a foam on top. It smells like what you'd expect.
As Sketch reaches up to take the third mug, the barkeep clicks his tongue and pulls the mug back.
"Sorry there little guy," he says, "but that's for your ma an' pop." He shifts his gaze from Sketch to Liam, an awkward and apologetic look on his face.
"Little?" Sketch snaps indignantly. "You believe this guy?" he sneers as he glares up at the bartender.

You can tell Sketch is about to say, or perhaps do, something that he might regret later. What does Liam do?

"This one's no child," says Liam, "no matter how much he acts it."

"Here," he says to Sketch, "Have mine too." He puts a mug in each of the halfling's hands.
