Drinks and Appetizers Between Shifts
Happy Hour in Waterloo for unwinding after work or filling the gap before dinner
A house margarita costs $3 between 2 p.m. and 5 p.m. at The King Mexican Bar & Grill, frozen versions run $5, and all appetizers drop by $3 off their regular menu price. This three-hour window runs Monday through Friday and targets the post-lunch, pre-dinner stretch when the dining room is quieter and the bar has open stools. You get the same kitchen output—nachos with house-made queso, street tacos on double corn tortillas, guacamole prepared in-house—at a lower check total simply because you walked in during a specific time block.
The pricing structure is built to fill the afternoon gap when most restaurants see a lull in traffic. Happy hour overlaps with the end of standard lunch service and the start of early dinner prep, so kitchen staff are already in position and ingredients are staged from the lunch rush. This means your order doesn't wait for a cold kitchen to warm up or for a prep station to restock—everything moves at the same speed as peak service, just with fewer tickets in the queue.
Confirm your arrival time before planning a group visit to stay within the 2 p.m. to 5 p.m. window.
Why Timing Affects What You Pay
The $3 house margarita uses the same tequila, lime, and triple sec ratio as the full-price version served at 6 p.m.—the only variable is the clock. Frozen margaritas at $5 come from the same machine, blended with the same mix and ice ratio, just ordered before the 5 p.m. cutoff. Appetizers follow the same logic: a $3 discount applies to items like chips and queso, street tacos, or loaded nachos, reducing the price without changing portion size or ingredient quality.
After you order, the kitchen preps your appetizer the same way it would during dinner service. Tortilla chips are fried in small batches so they stay crisp, queso is heated to the right viscosity for dipping without separating, and toppings like jalapeños, pico de gallo, and sour cream are added fresh. You'll see the difference between chips fried to order and chips that have been sitting under a heat lamp—they crack cleanly when you bite into them and don't go soggy after the first dip into salsa.
The happy hour window is fixed, so arriving at 4:55 p.m. gives you five minutes to order before pricing reverts to the regular menu. Groups aiming to share multiple appetizers or try several margarita flavors should plan to arrive by 3 p.m. or 3:30 p.m. to allow time for ordering and a second round if desired.
Common Questions Before You Stop In
Here's what people typically ask about the afternoon pricing and timing rules.
What happens if I order at 4:58 p.m.?
Your order locks in at happy hour pricing as long as it's placed before 5 p.m., even if the food arrives after the window closes.
How does the $3 appetizer discount work?
The discount applies to the regular menu price of any eligible appetizer, so if an item normally costs $10, you pay $7 during happy hour—no restrictions on which appetizers qualify.
Why are frozen margaritas priced differently than house margaritas?
Frozen drinks require blending and machine maintenance, which adds labor and equipment cost compared to pouring a house margarita from the bar well.
Can I order happy hour specials for takeout?
Happy hour pricing applies to dine-in orders only, so carryout and delivery orders during the same time window are charged at regular menu rates.
How crowded does the bar get during happy hour in Waterloo?
The 2 p.m. to 5 p.m. slot typically sees lighter traffic than evening service, making it easier to find seating and order without waiting, especially if you arrive closer to 2 p.m. or 3 p.m. rather than right before the cutoff.
The King Mexican Bar & Grill keeps the happy hour schedule consistent across weekdays, so you can plan regular after-work stops without checking for calendar changes. Call (319) 252-4704 if you need to verify timing or ask about group seating during the afternoon window.
