Shally can consider expanding her menu and services to attract more customers and increase sales. Here are some ideas:

1. Breakfast Items: Introduce breakfast items like mandazi, chapati, and boiled eggs, which are popular in Kenya and go well with kahawa (coffee).

2. Snacks and Bites: Add a variety of snacks such as bhajia, bajia, smokies, sausages, and chips. These are quick and easy to prepare and popular among many people.

3. Cold Beverages: Besides hot coffee, offer cold beverages like fresh fruit juices, smoothies, and iced tea to cater to those who prefer cold drinks, especially in hot weather.

4. Specialty Coffees and Teas: Introduce different types of coffee and tea, like spiced tea (chai masala), flavored coffees, or herbal teas to attract a diverse group of customers.

5. Pastries and Baked Goods: Include pastries like croissants, muffins, doughnuts, and cakes. These can be homemade or sourced from local bakers.

6. Healthy Options: Offer healthier options like fruit salads, vegetable sticks with dips, or yogurt parfaits to attract health-conscious customers.

7. Local Dishes: Introduce local dishes such as githeri, pilau, or ugali with vegetables, which can be a great way to attract people looking for a hearty meal.

8. Special Offers and Loyalty Programs: Implement special offers, discounts, or a loyalty program to retain customers and encourage repeat business.

By diversifying her menu and offering attractive deals, Shally can appeal to a wider audience and boost her sales.
