Text in Dropdown Menu width

Hi.

I have increased the width of dropdown box at https://www.happyhounds.ie/dog-boarding-kennels using the following CSS:

.main-navigation ul ul {
width: 300px;
}

I now need to increase the “text” to fill the dropdown box width.

At present the text is on two lines.

All help is greatly apprexciated and thank you in advance.
