"For under $30, eaters can head to Oliveira’s in Somerville and throw back as much braised oxtail or carne cozida as they wish. This Brazilian steakhouse has rodizio-style service — pay a fixed price, and an endless parade of servers will bring various cuts of meat to you until you flip a card from green to red to signal that you’re done — but there’s also a pay-by-weight buffet if you’d rather dine that way." - Terrence Doyle
